The length of fish were measured at 3 different lakes. Lake 1: 3.5, 4.2, 6.1, 5.2 Lake 2: 3.1, 3.2, 4.3, 2.1 Lake 3: 5.6, 7.1, 4.4, 4.1, 6.2 Is there evidence to suggest that the average length is not the same at all 3 locations? Group of answer choices There is not evidence to suggest the average length of fish is different at one of the lakes. There is evidence to suggest that the average length is different at one of the lakes. Enter the test statistic (to 4 decimal places)
Determine the minimum sample size required when you want to be 95% confident that the sample mean is within two units of the population mean and = 4.3. Assume the population is normally distributed. n =
The sample mean is often used as an estimator of the population mean because of its desirable properties, including: a. unbiasedness, consistency and efficiency Ob.consistency and minimum sampling error only Oc unbiasedness and consistency only Od. unbiasedness and efficiency only Oe. unbiasedness, consistency and minimum sampling error
Calculate the 1. Population and sample skewness, add interpretation 2. Exact and excess sample kurtosis, add interpretation
How many observations are in the data set? How do I calculate this in the "R" program?
In sampling situations, the population consists of: Select one: a. specific values like level of education. b. all cases that conform to a designated set of specifications. c. the entire physical world over a finite period of time. d. partial data utilized in characterizing the whole.
For this project you have to do the following: 1) list five different things that are normally distributed. Examples that you can't use since I came up with them: Shoe size, middle finger length, oxygen level, electricity bill, wait times on line to pay at target. You must give the website where you found that they are normal for each one of them. 2) measure yourself and use the normal distribution to find out what percent of the population is less than use. What this means is that for one of the five things in 1) you need to make sure that you can find the mean and standard deviation. So an example would be: I found the oxygen level mean and standard deviation to be 98.3 and 1.1. My oxygen level is 98.9. Using the normal distribution calculator I found that 69.3% of the population has a lower measure of that.
